Answer:
Step-by-step explanation:
We want the probability that the 35 cars are loaded onto the ferry. Therefore:
Since
μ=1.8 and σ=0.5 we have:
P(X<35 )=P ( X−μ<35−1.8 )=P((X−μ)/σ<(35−1.8)/0.5)
Since
(x−μ)/σ=Z and
we have:
Use the standard normal table to conclude that:
The amount of each of the 6 payments will be $41.50
Step-by-step explanation:
Given,
Cost of bike including taxes = $349
Down payment = $100
Amount left to pay = Cost of bike - Down payment
Amount left to pay = 349 - 100
Amount left to pay = $249
She agrees to pay in 6 equal payments, therefore, we will divide the total amount to pay by 6.
Amount to pay for one month =
Amount to pay for one month =
The amount of each of the 6 payments will be $41.50

Answer:
a) For this case we have 4 programs so then if we define the event R that a CD is tested we have the following probability for each test:
The failure probability for each program are given by:
For this case we assume that each test is independet form the others.
We can calculate the probability that all 4 programs works properly like this:
So then the probability that any program fails would be given by:
And if we use the fact that we have 4 possible test the true probability of interest would be:
b)
And replacing we got:
c) From part a we now that the probability that any program fails would be given by:
So then if we have 100 CDs the expected number of rejected Cd's are:
Step-by-step explanation:
Part a
For this case we have 4 programs so then if we define the event R that a CD is tested we have the following probability for each test:
The failure probability for each program are given by:
For this case we assume that each test is independet form the others.
We can calculate the probability that all 4 programs works properly like this:
So then the probability that any program fails would be given by:
And if we use the fact that we have 4 possible test the true probability of interest would be:
Part b
For this case we want the probability that it failed program 2 or 3
So then we can find this probability like this:
And replacing we got:
Part c
From part a we now that the probability that any program fails would be given by:
So then if we have 100 CDs the expected number of rejected Cd's are:
